This invention relates to a cleaning and disinfecting compound especially designed for household purposes although also adapted for universal application.

The object of the invention is to provide a compound of this character which is substantially inert at atmospheric dryness but which when mixed or dissolved in water he comes a potent cleansingand disinfecting agent and acts not only to remove dirt, scum and other deposits or discolorations from bath-room fixtures and the like, but also serves to destroy bad or foul odors as well as bacteria. The compound may therefore 5 be packaged and shipped and left standing indefinitely without hazard or inconvenience of any kind as it remains for all practical purposes entirely inactive unless mixed or dissolved in a bulk of water.

The compound may consist of a dry mixture of common salt, bisulphate of soda or nitre cake, any oxidizing agent of which potassium permanganate, potassium chlorate, potassium nitrate, or sodium nitrate may 5 serve as examples, and a substance such as corn starch, which tends to prevent lumping or consolidation.

In preparing a compound so constituted, the ingredients are preferably mixed in about 30 the following proportions:

ard or inconvenience ofany kind. If any reaction occurs it is very slight and does not extend beyond the exposed surface of the mixture and manifests itself merely by a faint odor of chlorine at the exposed surface s which is not easily detected.

The compound finds advantageous use in connection with closet bowls, traps or the like. -By merely sprinkling the compound freely into the bowl or trap and thereby dissolvingit in tliewater always contained therein the ingredients are caused to react to produce a small amount of chlorine which dissolves in the water as itis formed. After permitting the water. with the compound therein to stand for a short time the bowl or trapis flushed and all dirt, scum, incrustations, deposits and discolorations previously on the bowl or trap will-have disappeared. Moreover, bad'odors and bacteria will be destroyed and this efi'ective action will extend on down through the plumbing system. The

compound will not injure the bowl, trap or plumbing system. I

To a large extent the advantages and offectiveness of the compound result from the formation of hydrochloric'acid and the liberation of a small amount of chlorine when the compound is thoroughly mixedin the water,

the chlorine being taken up by the waterin rear Y rare which the compound is dissolved'and exercising' its cleansing, disinfecting and bleaching functions without escaping to the atmosphere. But the compound as a whole possesses peculiarly desirable cleansing and disinfecting properties v i I The chlorine liberated is in a practical sense controlled for, as it is taken upiby the water,- it does not escape to the air. By utilizing a small quantity of the oxidizing agent the amount of chlorine liberated is increased but still remains within the capacity of the water to absorb. However, even in the absence'of the potassium permanganate or other equivalent ingredient, enough chlorine is produced to renderthe compound efi'ective for many if not all purposes, the acid sodium sulphate acting in a sufficiently concentrated solution as an oxidizing When the potassium permanganate or equivalent is omitted, then the ingredients mixed in about the fol-.
